“The store has been clogged up with crowds,” Costco sent in a text message to customers in China, according to WTKR. “To provide you with better shopping experience, Costco will suspend business in the afternoon. Please don’t come.”

The company also released an apology and capped the number of customers in the store to 2,000.

The outlet covers an expanse of 14,000 square meters (more than 150,000 square feet), along with 1,200 parking spaces. Unfortunately, those spaces fell short on opening day, as management had to put up a sign saying that it takes three hours for new shoppers to find open slots in the parking lot.

Others stood outside for hours under the sweltering 97-degree Fahrenheit weather before managing to get in. Thankfully, no injuries were reported from the rampage.

The shopping craze proves to be understandable as Costco prices for general merchandise tend to be 30% to 60% lower than their market costs. Meanwhile, food prices are priced 10% to 20% less, according to the retailer.

Still, Costco’s long-term performance in the Chinese market is yet to be seen, as many foreign retailers have failed to understand consumer habits and eventually lost to local competitors. In June, French supermarket giant Carrefour had to sell 80% of its China business to a domestic company after repeated losses, the South China Morning Post noted.

Costco’s opening day, however, is not the first time Chinese shoppers have gone into absolute mayhem. In June, locals also went bonkers over a collaboration collection from Japanese fashion outlet Uniqlo and American artist Kaws.
